01) Docker installation

Installing Docker

You probably already know how to install Docker, but I wanted to include it because it may be useful to some and, of course, Docker is required to run the Cosmos Server, so we must first install it.

I'll only keep a Linux tutorial because I have no experience with Docker running on Windows.


  1. Go to your terminal, that's connected to your server. In my case, I use the PuTTY client for Windows.

  2. Execute this command:

    sudo -v ; curl -fsSL https://get.docker.com | sudo sh
  3. This will download and execute the official Docker installation script.

  4. When the script is finished, run the following command to enable you to run Docker without using sudo all the time:

sudo usermod -aG docker ${USER}
  1. This'll add your username to the docker group

NB: You need to exit and re-enter your terminal session, before it takes effect

On to the next step!
